RC19008AGND#KB0

Overview

The RC19008AGND#KB0 is a PCIe clock buffer manufactured by Renesas Electronics. It operates on a single supply voltage ranging from 2.97V to 3.63V and supports maximum frequencies up to 400MHz. The device features one differential input and eight differential outputs, utilizing HCSL or LVDS signaling standards. It is housed in a 40-VFQFPN package with dimensions of 5.00mm x 5.00mm x 0.90mm and a 0.40mm pitch. The component is designed for surface mount installation and functions within an ambient temperature range of -40°C to +105°C.

Feature Summary

• Supports 1:8 ratio with differential HCSL/LVDS inputs and outputs
• Operates at frequencies up to 400MHz with 2.97V to 3.63V supply
• Available in compact 40-VFQFPN (5x5) exposed pad package

Applications

• PCI Express timing systems
• High-speed data transmission interfaces
• Server and storage controller clock distribution

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and moisture sensitivity level. Confirm that the 40-VFQFPN package variant matches the required PCB footprint and thermal dissipation needs for the target application environment.

Selection Notes

Select this component when a single-ended or differential source requires expansion into eight matched output clocks for PCIe architectures. Ensure the system power supply remains stable between 2.97V and 3.63V to maintain signal integrity and compliance with specified electrical parameters.

Part Context

This part belongs to the Renesas clock buffer family designed for high-performance computing. It serves as a critical timing element in multi-lane serial link applications, providing low-jitter clock distribution to downstream components such as PHYs and controllers.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas portfolio that offer identical 1:8 ratios and package styles. Verify that any substitute maintains the same 400MHz frequency limit and voltage specifications.
